VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 242,252, dated May 31, 1881,

Application filed April 1, 1681.

To all whom it may concern Be it known that l, CARL BEGER, of the city of Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful lmprovementsin Velocipedes, of which the following is a specification.

This invention ielates to im firovements in velocipedes in which the propulsion is obtained by the rocking or oscillating motion of lo a seat arranged within the body of the vehicle; and the invention consists of a body supported by springs upon the hind axle and provided at its front end with a steering-wheel and lever. To fulcra of the vehicle-body is hung a rocking seat, which is connected by means of belts, cords, or chains with an alternately-working mechanism on the hind axle, by which continuous rotary motion is imparted to the same. The rocking motion may be assisted byahandlever at one or both sides of the seat, which are connected by pivot-links with fixed arms of the seat.

In the accompanying drawings, Figure 1 represents a sectional side elevation of my improved velocipede; Fig. 2, a rear elevation of the same, partly in vertical transverse section; and Figs. 3 and 4 are detail vertical transverse and longitudinal sections of the mechanism for imparting rotary motion of the hind Q axle.

Similar letters of reference indicate corresponding par-ts.

Referring to the drawings, A represents an open-bottomed wagon-body,which is supported by suitable springs on the hind axle, (J. The side walls of the body A diminish gradually in height from the rear end toward the front end, and are curved downward, as shown in Fig. 1, they being connected by a transverse bar, a, at the front part, from which extends a curved arm, I), to the upper end of which is swiveled thecenter boltof a yoke-shaped frame applied to the axle of the front guide-wheel. A lever, c, is applied to the center bolt of the 5 yoke-frame, by which the vehicle is steered in the usual well-known manner.

B represents a rocking seat, with a back and foot rest, which is hung by fulcra f to bearings at the inside of the vehicle-body A. For

the purpose of assisting the rocking motion of (No model.)

the seat B a lover, (I, is pivoted at its lower end to the side wall of the seat, and connected by a pivot-link, d, with a fixed crank-arm, d

of the seat, so that on oscillating the lever to and fro the seat will follow the motion of the same. The lever is especially useful in starting the motion of the seat, or in assisting the same when passing over rising ground, and, if desired, a second lever may be arranged at the opposite side. The rocking motion of the seat B is utilized for the forward propulsion of the vehicle by means of a power-transmitting mechanism, D, which changes it into a rotary motion of the hind axle, O. The transmitting mechanism D is applied to the hind axle, O, 6 and is shown in detail in Figs. 3 and 4. It consists of two collars, g, which are rigidly keyed to the axle G, and of loosely-turning flanged disks h h, which are arranged sidewise of the collars g in such a manner that their flanges form contact with each other and form a kind of box around the collar g. Each disk It is provided at its outside with a central pulley, having grooves h, to each of which a cord, belt, or chain, 1 and m, is applied. To the in- 7 ner collars, g, are hinged spring-acted dogs t in such a manner that when either of the disks h h is turned in the direction of the arrow, Fig. 3, the axle O is carried along, while by turning the disk in the opposite direction the dogs are released from the flanges of the disks, and admit thereby the turning of the disks on the axle.

The cords, belts, and chains 1 and m are wound in opposite direction to each other upon the grooved pulley h h, and are connected at their opposite ends respectively to points at the upper and lower part of the rocking seat B. While the cords, belts, or chains 1 limpart by the rocking motion of the seatB a forward 0 turning motion to both disks h h, and thereby to the axle O, the belts or chains m m are simultaneously unwound, so as to carry that disk h which is not at that moment in use for forward motion back to its former position, 5 ready to be engaged again by the dogs i for forward motion, as shown in Fig. 3. The alternate winding and unwinding of the cords, belts, or chains land at impart a continuous rotary motion to the axle O, and consequently 10o lllt llllllllllll l lw a regular forward propulsion of the vehicle. The same propelling mechanism may also be employed for railroad hand-cars, marine velocipedes, and similar vehicles,in which case, however, the transmitting mechanism 1) has to be placed 011 an auxiliary axle, which is connected by means of gearing, so that the vehicle can be moved in forward or backward direction.

Havingthus described myinvention, I claim as new and desire to secure by Letters Paten t-- 1. As an improvement in velocipedes, the combination of a rocking scat. B, hung to an open-bottomed body, A, with transmitting mechanism D, applied to the hind axle, and with cords, belts, or chains l l m m connected thereto, so as to change the rocking motion of the seat into a continuous rotary motion of the axle, substantially as and for the purpose set forth.

2. As an improvement in velocipedes, the combination of an open-bottomed wagon-body, A, rocking seat-B, suspended therein, connect ing-cords l L and m m, flanged disks h h, having grooved pulleys h h, and interior collars, g 9, having hinged and springacted dogs '6 i, substantially as and for the purpose set forth.

3. As an improvement in velocipedes, the combination of an open-bottomed body, A, rocking seat B, suspended therein, transmitting mechanism D, applied to the hind axle, whereby the rocking motion of the seat is changed into a rotary motion of the axle, and a hand lever or levers, d, pivoted to the rock ing seat and connected to a fixed arm or arms, d back of the lever, to assist the rocking motion of the seat, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 5th day of February, 1881.

CARL BEGER.
